  • Patent number: 10260740
    Abstract: A method generates superheated steam using heat generated in a boiler of an incineration plant. The pre-superheated steam is fed to a final superheater that includes a plurality of final superheater pipes through which the pre-superheated steam is guided and is finally superheated in the process. The final superheater pipes (are arranged at least partially in at least one cavity (formed in an interior of a wall element of the boiler and/or of a bulkhead arranged in the boiler. The cavity is closed off on a boiler side at least partially by a refractory material layer and is flowed over by flue gas released during combustion. A secondary medium flows through the cavity and is heated via heat transfer from the flue gas via the refractory material layer. The heated secondary medium is fed via a secondary medium feed line to a secondary heat exchanger.
